Upgraded to Goodyear G-614`s recently on the original Tredit wheel recertified for 110 psi. Dealer said he called Tredit and they said the original valve stems were rated for 110 psi. I got to thinking and emailed Tredit myself and was told the valve stems would handle 100 psi. I do not think my unit requires the full 110 psi per the load and inflation charts. I weighed my 3400 alone on Cat Scales and it was 13,000# with tanks empty. If I subtract a ball park pin weight of 2200# that leaves a load of 10,800 on the axles. If I read the inflation table right that would indicate running 70 psi. That seems too low and not safe. Tredit says they can send me valve stems to accept 110 psi. Opinions?

So long as you NEVER exceed the 100psi in the tires there should be no problem. I am heavier with 12,600lbs over my wheels so I run my 614's at 95 psi. I would think that 70 is a little low. Just my unofficial opinion.....
